Estimates are the posterior means (and 95% credible intervals) for additive genetic variance (V_A), covariance (COV_A) and correlation (r_A), permanent individual variance (V_PI), social mate variance (V_Soc), year variance (V_Y) and covariance (COV_Y), cohort variance (V_C) and covariance (COV_C), residual variance (V_R) and covariance (COV_R), latent‐scale heritability (h² _lat) and slope of the regressions on individual coefficient of inbreeding (β_f). Intercepts, and male age effects on ARS, are in Table S3.
